images: Add arch-toolbox image definitions for Arch Linux

This is the definition of the arch-toolbox image for Arch Linux that
plays well with Toolbx.

Today, it's published at quay.io/toolbx-images/archlinux-toolbox:latest,
but the name of the published image will be changed to arch-toolbox [1]
to match the os-release(5) ID on Arch Linux.  The convention of naming
the Toolbx images according to the os-release(5) ID is deeply ingrained
in the Toolbx code base.  It will be better to keep things simple by
continuing that practice, instead of adding a one-off exception.

Maintenance of this image has been passed to Morten Linderud.
